Sunset Savanna is huge and runs all along the east side of Kidani which side has about 85% of all savanna view rooms at Kidani. The other savanna for Kidani, Pembe, is much smaller (just opened) and to the north of the building. The following is a list of animals for Sunset, Arusha, and Uzima savannas (not sure all are in all three, although giraffes and many others are; Arusha is in center of the Jambo building and Uzima to the east of Jambo, the west side of Jambo also faces Sunset):
Anikole Cattle
Bongo Blesbok
Eland
Grant's Zebra
Greater Kudu
Impala
Reticulated Giraffe

White-Bearded Wildebeest

As to Pembe, Disney's press releases mention the following:
okapi, yellow-backed duiker, Red River hogs, nyala, impala, waterbuck, spur-winged geese and blue crane.
Those announcements also mentioned that the other savannas will not have the okapis and Pembe will not have the giraffes.
